Jenco Instruments is a manufacturer of water quality testing instruments. According to its official website, it has been in the industry since 1973, and claims to have launched the world's first portable digital pH meter. The company's business focuses on measuring water quality parameters including pH, ORP, conductivity, TDS, salinity, dissolved oxygen, and temperature, with operations and support locations covering San Diego (US), Shanghai, and Taipei.
Jenco has a relatively complete product line, including test pens, portable meters, laboratory benchtop meters, industrial online meters, electrodes, and accessories.
For B2B customers, it also offers OEM, private labeling, and ODM services, with customization available for appearance, panels, packaging, instruction manuals, and even complete product design.
The official website does not publish retail prices, and product pages use an "Add to Quote" function to generate request for quotation forms. The homepage mentions that demo orders can enjoy a discount of up to 60%, but does not specify the applicable conditions. Jenco explicitly states that it does not sell directly to end users, and instead relies on distribution partners. As a result, actual pricing, delivery lead times, and after-sales services usually need to be confirmed through dealers or the sales team.
Pros: Deep industry experience, wide product coverage, and the ability to both supply branded products and provide manufacturing/contracting services. The official website also highlights multi-layer quality inspection, supply chain experience, and long-term distribution partnerships.
Cons: Purchasing transparency is mediocre, with no public online pricing or direct purchase portal. Chinese-language content is limited, and some pages mix Chinese and English text. For casual users, model selection and technical parameters are quite specialized, and assistance from sales or dealers is often required.
It is suitable for laboratories, water treatment companies, agricultural planting, aquaculture, industrial process control, system integrators, as well as brands and distributors looking for water quality instrument OEM/ODM services. It is not a good fit for individual users who simply want to purchase an entry-level water test pen and check out online immediately.
The official website can be accessed directly without any proxies. The company has manufacturing, R&D, and sales/customer support operations based in Shanghai, making it relatively friendly for Chinese procurement and supply chain collaboration. However, specific purchasing channels still need to be confirmed via official website contact or local distributors.
